Exposure of sagittal slices of mouse brain to MPTP (100 pM) caused inhibition of mitochondrial NADH-dehydrogenase activity.
Other cytochrome P-450 inhibitors, namely, piperonyl butoxide and SKF 525A were found to offer protection against MPTP induced neurotoxicity in slices without affecting monoamine oxidase activity.

Incubation of mouse brain slices with various concentrations of MPP+ (1-100 microM) resulted in dose-dependent inhibition of mitochondrial enzyme NADH-dehydrogenase (NADH-DH) and leakage of the cytosolic enzyme lactate dehydrogenase from the slice into the medium.
MPP (+)-induced toxicity was abolished by pretreatment of the slices with inhibitors of monoamine oxidase (MAO; pargyline and deprenyl) or inhibitors of P450 (piperonyl butoxide or SKF-525A) or dopamine uptake blocker (GBR-12909), as measured by the activity of NADH-DH in slices and leakage of lactate dehydrogenase from the slice into the medium.

However, other subcellular marker enzymes such as Na (+)-K+ATPase (plasma membrane), cytochrome c oxidase, isocitrate dehydrogenase, NADH-dehydrogenase (mitochondrial), N-acetylglucosaminidase, acid phosphate (lysosomal), glyceraldehyde-3-phosphate dehydrogenase and enolase (glycolytic enzymes) were unaffected even at the highest tested concentrations of MMEA (10 and 100 microM).
Pretreatment of slices with piperonyl butoxide and metyrapone, inhibitor of cytochrome P-450, also prevented the toxicity of MMEA.
